Driving and Operating specification D7467 (Biodiesel blend, B6 - B20). Biodiesel is an emerging product, and its quality can vary widely. To reduce the risk of poor quality fuel, we recommend that biodiesel users purchase biodiesel blends from a BQ-9000 certified marketer. A listing of certified marketers can be found at www.bq-9000.org. If there are questions about the biodiesel-containing fuels you are using, contact your fuel supplier. We neither encourage nor discourage the use of biodiesel blends for vehicles. As a renewable fuel, biodiesel provides some environmental benefits. However, biodiesel has unique properties and needs to be handled differently than diesel fuel. Its use presents additional risks and may not be appropriate in all situations. Certain vehicle operating modes increase these risks and should be avoided. Read further to determine if your driving habits are compatible with the use of biodiesel. . 9-57 biodiesel. Storage at hot ambient temperatures will accelerate biodiesel degradation. When vehicles will be stored for extended periods of time (greater than one month), they should be run out of biodiesel to below one-quarter tank, refueled with conventional Ultra Low Sulfur Diesel fuel, and driven several miles before storage. . { Caution Certain driving patterns are not compatible with biodiesel use. It is the operator 's responsibility to ensure that biodiesel in the vehicle's tank does not lead to engine, fuel system, or exhaust after-treatment system damage. Biodiesel fuel quality degrades with time and exposure to high temperature much more quickly than conventional diesel fuel. More frequent refueling provides the best opportunity to have a supply of fresh fuel. Owners who have very low fuel usage or who have vehicles stored for extended periods of time should avoid the use of Biodiesel gels sooner than conventional diesel fuel at cold temperature, and biodiesel fuel requires proper blending for winter time operation. Fuels improperly blended for cold temperature operation may result in restricted fuel filters and degraded vehicle performance. Your vehicle is equipped with a fuel heating system to provide a level of protection against filter plugging from gelling (waxing) of conventional diesel fuel and biodiesel blends. However, the system will not prevent all cases
